Materials Data on SrLiAs by Materials Project
LiSrAs crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing LiAs4 tetrahedra. There are a spread of Li–As bond distances ranging from 2.69–2.93 Å. Sr2+ is bonded in a 5-coordinate geometry to five equivalent As3- atoms. There are a spread of Sr–As bond distances ranging from 3.18–3.27 Å. As3- is bonded in a 9-coordinate geometry to four equivalent Li1+ and five equivalent Sr2+ atoms.
